Vintage Digital


AMS (Advanced Music Systems) was founded in 1976 by Mark Crabtree and Stuart Nevison, both of whom were aerospace engineers. The first product designed by the company was the AMS DM-20 Tape Phase Simulator. This initial AMS product was used by ELO, 10cc and Paul McCartney, who used it on the Wings’ London Town album in 1978. The real breakthrough for AMS however was to come, and in 1978 they released the AMS DMX 15-80 digital delay line. Later the DMX 15-80s included “loop triggering” launching the use of digital sampling. The DMX later included pitch changing and up to 32 seconds of delay. These units can still be found in studios the world over. Perhaps the most revered product from AMS however, is the AMS RMX 16 digital reverb. The AMS RMX 16 was released in 1981, and included a reverb patch called Non Lin, referring to non-linear or ‘gated’ reverb.

This patch was developed with the help of Hugh Padgham, the creator of the gated reverb effect, discovered when working with Peter Gabriel, and made famous by Phil Collins with his Face Value album. The Non Lin preset was used for most of the 1980s from the time the AMS RMX 16 was released. Another patch on the AMS RMX 16 was Ambience, and again, it was heavily used, and is still in use today. AMS was floated on the London Stock Exchange in 1985. Siemens bought AMS in 1990 and merged the company with Neve Electronics in 1992. Crabtree acquired the combined firm in 1995, becoming the sole owner of AMS Neve. AMS Neve continues to manufacture professional recording equipment, including a reproduction of the AMS RMX 16 in 500 rack format, released in 2020.

AMS/Neve AMS RMX16 Digital Reverb

What do you do when an old reverb is still so popular after nearly 40 years? You update it and release it once again. The AMS RMX16 was the world’s first microprocessor-controlled, full-bandwidth digital reverberator and characterized an enormous number of seminal recordings from the 1980s onwards. Its designer’s love for music and experience in the aerospace industry meant it was way ahead of its time on release.

AMS RMX 16 Digital Reverberation System

Unlike its mechanical counterpart the AMS RMX 16 system does not require special installation. This, together with the large reduction in size, the superior signal to noise performance and the greater bandwidth, gives the AMS RMX 16 significant advantages over old-fashioned mechanical reverberation systems.

AMS DM2-20 Tape Phase Simulator

The AMS DM2-20 tape phase simulator is the result of extensive research into the requirements and needs of the recording industry, for accurate simulation of tape phasing. Unlike other units of this kind, which solely mix the delayed signal with the original, the DM2-20 uses two independent delay lines to allow true ‘over the top‘ tape phase simulation.

AMS DMX Series Keyboard Interface & Chorus Controller

The AMS DMX Series Keyboard Interface and Chorus Controller is an ultra rare device to add on to the AMS DMX 15-80S Digital Delay. The chorus controller can be used to add functionality and effects to the DMX 15-80S.

AMS DMX 15-80S Stereo Digital Delay

The AMS DMX 15-80S is a true stereo microprocessor controlled digital delay line. Originally designed to meet specifications laid down by the British Broadcasting Corporation for equipment to be supplied to them, it offers two completely independently delayed channels with precisely controlled delay times.
